Review sheet idea

When I give students a review sheet for a test, I like them to go over the answers in pairs. So, I created the attached sheet. Each student gets a sheet. They put their own name at the top. Then, they choose three people to pair up with. Those names go in the slots for Partner #1, Partner #2, and Partner #3. The students complete the review sheet for homework. Then, the next day, they pair up with 4 different people. With each person, they have to agree on the answer to each problem and write that answer on the sheet. Then, after 15-20 minutes, I stop them and go over any questions that the students have. They then switch partners for the next section of the review sheet. We continue in this way until they have gone over the whole review sheet.
